Cory Jane has finally upgraded to a full driver's licence, taking his driving test after 12 years on restricted duties because "I had pressure put on me from the New Zealand Rugby Union".

"I feel like I'm a grown-up now."

"They wanted to take the car back if I didn't get my full," Jane told Fairfax Media on Wednesday. "Since I'd been on my restricted for 12 years I thought I'd better just go for it. I'm not sure [why I never got it before this week]. I got told you could drive with the kids in the car just like a full licence. I've never had a kick in the bum until now when the New Zealand Rugby Union made all the boys [All Blacks] do it. Jules [Julian Savea] did his straight after me. I feel like I'm a grown-up now."

Jane previously could not drive passengers without a supervisor in the front seat who had held a full licence for at least two years. Nor could he drive alone between the hours of 10pm and 5am.
